Ores and where to find them: a map of the underground.
Each layer of the planet holds its own ores at set depths. This page lists every ore, how deep to dig, how it occurs and which tool breaks it.
Reading the tables
- Depth is in metres below sea level on the home planet. A negative number means above sea level, inside mountains.
- Vein ores run in chains of blobs. Pocket ores sit in single blobs.
- Weight is how common the ore is compared with its neighbours in the same layer (higher is commoner).
- Tool is the tool tier needed to break it. See Tools and tiers.
- Smelts to is the result in a Furnace and the share of each unit you keep. See Smelting and fuel.
Home is 3000 metres from surface to core. The layers on home are: Crust 0 to 300, Upper Mantle 300 to 1200, Lower Mantle 1200 to 2200, Outer Core 2200 to 2800 and Inner Core 2800 to 3000. The deeper you go the hotter and higher the pressure, so see Going deep before you dig.
Crust
Tools from Flint to Iron reach everything here, and the crust is where you first find coal, copper, tin and iron.

Extra sources: Malachite also turns up a few blocks under the surface almost everywhere, so a flint pick reaches copper early. Clay lies in pale lenses a few blocks under low and middling ground, in banks and river beds; a shovel digs it.

Uraninite and Monazite are radioactive: the Corelight Age begins when your world has dug 60 blocks of Uranium, Thorium, Uraninite or Monazite. See The eight ages.
Lower Mantle (1200 to 2200 m)
| Ore | Depth (m) | Shape | Weight | Tool | Notes |
|---|---|---|---|---|---|
| Sperrylite | 1200 to 2200 | Vein | 2 | Iron | Smelts to Platinum 55% |
| Iridium | 1400 to 2200 | 0.6 | Steel | Pure metal | |
| Osmium | 1400 to 2200 | 0.6 | Tungsten | Pure metal | |
| Palladium | 1200 to 2200 | 0.8 | Iron | Pure metal | |
| Tantalum | 1200 to 2200 | 1 | Steel | Pure metal | |
| Molybdenum | 1200 to 2200 | Vein | 1.2 | Steel | Pure metal |
| Vanadium | 1200 to 2200 | Vein | 1.2 | Steel | Pure metal |
| Tungsten | 1300 to 2200 | 1 | Tungsten | Pure metal | |
| Chromium | 1200 to 2200 | 1 | Plasma (Coreforged only) | Pure metal | |
| Diamond | 1600 to 2200 | 0.2 | Coreforged | Pure carbon | |
| An unidentified ore | 1200 to 2200 | Vein | 9 | varies |
"Pure metal" ores are already a metal. Use the block as it is, or break it into pieces for tools and alloys. You need Vanadium for Titanium Alloy and Tungsten for Tungsten Carbide.
Outer Core (2200 to 2800 m)
| Ore | Depth (m) | Shape | Weight | Tool |
|---|---|---|---|---|
| Pyrrhonite | 2200 to 2800 | Vein | 4 | Plasma (Coreforged only) |
| Nickel | 2200 to 2800 | 2 | Bronze | |
| Platinum | 2200 to 2800 | 0.8 | Bronze | |
| An unidentified ore | 2200 to 2800 | Vein | 8 | varies |
The rock of the Outer Core itself is built of Taenite and Kamacite, two metals you can alloy into a Coreforged tool head. See Alloys and the Forge. Pyrrhonite is a glowing metal that is already Coreforged.
Inner Core (2800 to 3000 m)
| Ore | Depth (m) | Shape | Weight | Tool |
|---|---|---|---|---|
| Stellarite | 2830 to 2990 | Vein | 5 | Coreforged |
| An unidentified ore | 2800 to 3000 | Vein | 5 | varies |
The rock of the Inner Core is Hexaferrum, a pale metal (hardness 9.2) that makes an excellent suit shell. Stellarite is the key to Nova Alloy.
Unidentified ores
Every planet has its own invented ores, so no two worlds have the same set. Their properties come from the layer: deeper ones are harder, denser, hotter-melting and rarer, and more of them are exotic or radioactive. In your bag they show as Unidentified ore, Unidentified metal, Unidentified crystal, Unidentified organic or Unidentified anomaly until you analyse them at a Lab Bench. Then you can give them your own name. See Research and the Lab Bench and How materials work.
Geodes
Geodes form in the crust and upper mantle. Their shells are made of Quartz, Amethyst, Fluorite, or an invented gem.
Other worlds
Another planet's ground holds nothing of Home's. Each of Home's ores is replaced by an invented stuff of that world, in the same places and amounts. An ore of a metal is a metal of its own, and a fuel is a fuel, so you can still smelt, forge and build there. On top of that, each kind of world has its own elements in its crust:
| World | Elements (depth in m) |
|---|---|
| Jungle and ocean worlds | Phosphene (10 to 200), Neblium (60 to 260) |
| Desert worlds | Thrumite (30 to 260), Phosphene (80 to 260) |
| Ice worlds | Neblium (0 to 180), Phosphene (40 to 220) |
| Volcanic worlds | Ashglass (-60 to 200), Thrumite (60 to 260) |
| Acid worlds | Vitriolite (-40 to 140), near the surface |
- Vitriolite: hardness 6.5, acid-proof crystal. It is what an Acid Suit is best made of.
- Phosphene: hardness 3, a very bright, reactive crystal.
- Thrumite: hardness 7.5, a magnetic metal ore.
- Neblium: hardness 2.2 and very light (density 0.35), a crystal that lifts.
- Ashglass: hardness 7, a heat-proof crystal.
These start out unidentified, like the core's own invented materials.
Tips
- A beginner needs only the crust: Malachite, Cassiterite and Hematite are all common.
- Dig sideways along a vein. Veins are chains, so one find usually leads to more.
- Keen-eyed explorers can research ways to feel buried things from further off: see Research and the Lab Bench.
- The recipe book's red "missing" lines tell you where to find each ingredient.
